Denver Police say two Denver sheriff's deputies were serving a felony arrest warrant Morales in the 300 block of Park Avenue West at a Denver Housing Authority property. The warrant was for burglary, assault and harassment.

According to Denver Police, Morales came to the door with a gun. She shot a male sheriff's department deputy in the hand. It is unknown at this time how close Morales was to the deputy at the time of the shooting. The deputy who was shot is in fair condition with non-life-threatening injuries and was transported to the hospital.

After the deputy was shot by the suspect, another deputy returned fire. Morales was pronounced dead at the scene.

Two small children, a 5-year-old girl and a 2-year-old boy, were in the home at the time of the shooting. They were not injured but transported to the hospital as precautionary measure.

There is no word on if anyone else was in the home at the time.

Sources tell 9NEWS both deputies serve on the sheriff's office fugitive warrant detail. Serving warrants is all they do.

There is only two of them in this unit. Both of them have been with the Denver Sheriff's Department since 1994, and on the fugitive detail for about five years, sources tell 9NEWS.

9NEWS has learned the men don't wear a uniform, they wear civilian clothes and drive an unmarked car. In a job where they have to find people who don't want to be found, they have to be inconspicuous, sources tell 9NEWS.

However, when they find the person who needs to be served, they often wear a jacket and a hat identifying them as sheriff's Deputies. They also wear a badge around their neck, showing who they work for.

Sources tell 9NEWS the deputies always have to identify themselves when making an arrest.

The deputy who fired his weapon is on paid administrative leave which is standard procedure.

Polis Elementary School near the shooting was placed on lockdown during the investigation. It has since reopened.
